In his final novel, Mark Hansom eschews the supernatural for a mystery filled with psychological terror. 'The Madman' was published just as WWII was impacting England, and, while all of Mark Hansom’s novels are scarce, 'The Madman' is a legendary rarity, with less than a dozen copies known to exist. In this book, Hansom ably demonstrates that he can write the non-supernatural thriller as deftly as he handles the other genre. We have no way of knowing what he would have accomplished or what direction his fiction would have taken had he written more. As the leading authority on Mark Hansom, John Pelan, surmises, it’s very likely that the man who wrote under the Hansom by-line died in WWII. This last novel serves as a testimony to the versatility of the author. This edition features two introductory “Theoriesâ€, by John Pelan and Thor Dockweiler, each hypothesising as to the identity of the real author behind the Hansom pseudonym. Another special addition to this long-overdue reissue of the author’s last novel is a short story by Hansom, ‘The Last Trick’ (originally published in an Australian magazine in 1937). This well-crafted story is the perfect complement to Hansom’s sole non-supernatural novel.
